Concrete sealing hardener
The wear resistance is one of the important indexes of concrete, which affects the use effect and durability of the floor.In order to ensure or improve the wear resistance of the floor, we must first understand the factors that affect it.
Abrasion causes a large local stress in the concrete, so the strength and hardness of the surface concrete directly affect the wear resistance.In addition, the compressive strength is the main determinant of the wear resistance of concrete, and the minimum value depends on the erosion strength of the environment.In general, high strength concrete has a higher wear resistance, the compressive strength can be increased from 50MPa to 100MPa, wear resistance can be increased by 50%, 150MPa concrete wear resistance is equivalent to high quality granite.
In the process of concrete construction, it is easy to directly affect the performance of the concrete surface, reduce the water-cement ratio of the concrete surface, and improve the compactness;Vacuum dehydrating agent;Avoid bleeding;Good and proper maintenance is also essential.Curing time is two times of ordinary concrete, can achieve good wear resistance.
Aggregate also has a certain influence on the wear resistance of concrete, so high strength and hard aggregate should be used.And do not need high wear-resistant aggregate can be prepared to wear good concrete, belongs to the porous structure, impact resistance is poor.At the same time, the capillary cracks in the concrete will accelerate the abrasive failure.At this point, concrete sealing hardener can be used to treat the floor.The material can effectively penetrate into the floor, close the pores of concrete itself and the gap formed by aggregate, greatly improve the compactness of the floor, increase the strength, hardness and compressive strength of the floor, so as to improve the wear resistance of the floor.
